At the Beijing National Stadium, Honeywell contributed to the success of the 2008 Summer Olympic Games. Inside the stadium's walls is closed cell spray foam applied with Honeywell's Enovate® blowing agent, creating a seamless environmental barrier. Because it adds to structural strength, it makes roofs more durable and easier to maintain. And with the highest R value per inch of any insulation, closed cell spray foam can reduce heating and cooling bills by 40%.
